[单选题]
Which of the following pairs of graphs represents lg,v/ycpwz s25 (0kb9xd25 fvfz l+iyhow the electx y k/g8c/27okj6an nsric field and the electric potential due to a hollow conducting sphere vary gkn/cjsk a72n/6 x8o ywith distance from the center? The origin of the graph represents the center of the sphere.

A.
B.
C.
D.


参考答案:  B


本题详细解析:

Explanation​:

The electric field vector inside a hollow conductor is zero. Due to the lack of field inside the sphere, the electric potential is constant and equal to the surface value .

Outward from the surface of the sphere, the electric field varies with the inverse‾inverse​ square of the distance from the center while electric potential decreases inversely with the distance from the center.
